[BUG] Touch reaction slow

[AlexanderTonn]

:bug: Describe the bug

• it takes about 3-5s for detecting touch input
• it seem's like that the microcontroller is under high load or the SPI bus clock is too slow for my tasks

 :bangbang: To Reproduce**

Steps to reproduce the behavior:

• tried to figure out whether the "map" function takes a lot of computing power, but this isn't it.

  touchPoint.x = map(touchPoint.x, TOUCH_X_MIN, TOUCH_X_MAX, tft.width(), 0);
  touchPoint.y = map(touchPoint.y, TOUCH_Y_MIN, TOUCH_Y_MAX, 0, tft.height());

• touch irq is currently not working, see also: Issue 19 (i can't try to figure out whether the cause is the touch.getPoint()in each iteration)

Reason for the issue was the usage of "delay()" in the controlLogic.ino

// Set Relays on Mppt Mode
void relayOnMppt() {
  auto ms = secondToMs(uiSett_PVswitchingDelay);
  digitalWrite(K2_INVERTER_AC, LOW);
  delay(ms);
  digitalWrite(K1_INVERTER_DC, LOW);
  delay(ms);
  digitalWrite(K3_MPPT_CHARGER, HIGH);
  byModeActual = BATTERY_MODE;
}
void relayOnInverter() {
  auto ms = secondToMs(uiSett_PVswitchingDelay);
  digitalWrite(K3_MPPT_CHARGER, LOW);
  delay(ms);
  digitalWrite(K1_INVERTER_DC, HIGH);
  delay(ms);
  digitalWrite(K2_INVERTER_AC, HIGH);
  byModeActual = INVERTER_MODE;
}
